Estudou-se patógenos associados às formigas encontradas no Hospital Escola da Universidade Federal do Triângulo Mineiro, Uberaba/MG. Três espécies de formiga foram identificadas: Tapinoma melanocephalum, Pheidole sp e Paratrechina longicornis. Os principais microorganismos encontrados foram Staphylococcus sp, bacilo Gram-positivo, Pseudomonas sp e Micrococcus sp. Os resultados das coletas foram analisados, segundo o número de colônias e os diferentes microrganismos isolados, aplicando teste t de Student. A análise estatística revelou diferença significativa apenas para Staphylococcus sp com p = 0,005. É possível que formigas e agentes patogênicos tenham associações mutualísticas, e que a análise dessa relação possa levar a novas estratégias de controle, com ênfase não apenas nos insetos, mas especialmente em qual agente está associada essa espécie de inseto.

Ant-hemipteran mutualism has been well documented, and many studies have reported the interference competition between ant species for the mutualism. However, little is known on how this interference competition impacts the reciprocally beneficial association. Previous studies demonstrated that the invasive mealybug Phenacoccus solenopsis (Tinsley) has established close mutual relationship with the ghost ant Tapinoma melanocephalum (Fabricius). The sympatric ants, Paratrechina longicornis (Latreille) and Tetramorium bicarinatum (Nylander) were frequently observed to compete for nutrient honeydew produced by P. solenopsis with T. melanocephalum. Herein, we investigated the effects of interference competition between the ant species on the ant-mealybug interactions. Phenacoccus solenopsis benefited from the tending by T. melanocephalum and P. longicornis. Interference competition between T. melanocephalum and P. longicornis interrupted the mutualism, suppressed the trailing activity of both species, but negligibly influenced the parasitism of Aenasius bambawalei Hayat, a solitary endoparasitoid of P. solenopsis. Harmonia axyridis, a predator of P. solenopsis, showed a significant avoidance when encountering with T. melanocephalum or P. longicornis, but not T. bicarinatum. Ant workers showed higher aggressiveness and lower exploratory activity when T. melanocephalum encountered P. longicornis. However, competition between T. melanocephalum and T. bicarinatum seldom influenced the trailing and exploratory activity of T. melanocephalum. It is concluded that interference competition for mutualism between ant species can mediate ant-mealybug associations and the fitness of mealybug colony. Our results also demonstrate that the effects of interference competition between ant species on ant-mealybug mutualism are varied among ant species.

A survey of structure-invading pest ants was conducted at 17 healthcare facilities (HFs) in Singapore using the index card method. A total of 18 species (Anoplolepis gracilipes (Fr. Smith), Meranoplus sp., Monomorium destructor ( Jerdon), Monomorium floricola ( Jerdon), Monomorium pharaonis (L.), Monomorium sp., Odontomachus sp., Oecophylla smaragdina (F.), Pachycondyla sp., Paratrechina bourbonica (Forel), Paratrechina longicornis (Latreille), Paratrechina pubens (Forel), Pheidole megacephala (F.), Pheidole parva (Mayr), Pheidole sp., Tapinoma indicum (Forel), Tapinoma melanocephalum (F.) andTetramorium bicarinatum (Nylander)) were trapped. Of these, the most common species were P. parva (25.9%), P. megacephala (25.2%), P. longicornis (14.1%), M. pharaonis (9.6%), and T. indicum (8.1%). Most of these ant species were found in and around the premises.

The purpose of this research is to find out the species of soil ants in the residential area. The sampling method is hand collecting and baited trap (tuna and honey). There are 8 species found: Acanthomyrmex sp., Solenopsis germinata, Monomorium pharaonis, Pheidole megacephala, Paratrechina longicornis. Tapinoma melanocephalum, Camponotus ligniperda, Diacamma intricatum. The most numerous species, namely Pheidole megacephala and the least species, namely Diacamma intricatum. Ant species diversity tends to increase, as human activity decreases

RESUMO As formigas urbanas são consideradas um problema grave na saúde pública pela capacidade de ocupar todos os ambientes e por serem vetores mecânicos de micro-organismos. O presente trabalho teve por objetivo verificar as espécies que ocorrem em estabelecimentos ligados a área da saúde, bem como os microrganismos veiculados por essas espécies. Em um total de 1.629 coletas realizadas de outubro a dezembro de 2007em um hospital, na Secretaria de Saúde e em um laboratório de análises clinicas, utilizando-se iscas atrativas não tóxicas, as seguintes espécies foram registradas foram registradas: Tapinoma melanocephalum (Fabricius, 1793); Monomorium pharaonis (Linnaeus, 1758); Paratrechina fulva (Mayr, 1862); Pheidole triconstricta Forel, 1886; Pheidole sp.1; Pheidole sp.2; Pheidole sp.3; Pheidole sp.4; Camponotus atriceps (Fr.Smith, 1858); Brachymyrmex sp.; Dorymyrmex sp.

AbstractThe experiment was conducted at residential areas Sirimau forest with three sampling methods, which were hand collecting, bait trap (sugar and tuna) and pitfall traps from July to September 2011. The study aims to determine abudance of ants in residential areas in Ambon Sirimau Protected Forest areas. The results of study found 16 species of ants in total reaching 14.913. The most dominant types are Odontoponera denticulata, Pheidole megacephala, Technomyrmex albipes, Tetramorium simillimum, Tetramorium bicarinatum, Tapinoma melanocephalum, Paratrechina longicornis and Anoplolepis gracilipes. Total abudance of ants is 2.789 classified as moderate by spread of number of individual spread and of community stability. The abudance of ants is strongly influenced by light intensity, temperature, humidity, wind, water and season. Difference of temperature micro, light climate, humidit, interspecific competition, availability of variety of food sources, habitat quality and human activities also affect the abudance of ants. Another finding showed invasive ants, they were Soleonopsis geminate, Paratrechina longicornis and Anoplolepis gracilipes. Keywords: Abudance of ants, invasive species, protected areas, settlement areaAbstrakPenelitian dilaksanakan pada areal pemukiman dalam Hutan Lindung Sirimau dengan tiga metode pengambilan sampel yakni hand collecting, bait trap (umpan gula danÂ ikan tuna) dan pitfall trap dari bulan Juli hingga september 2011. Penelitian bertujuan mengetahui keragaman semut pada areal pemukiman dalam kawasan Hutan Lindung Sirimau Ambon. Hasil penelitian menemukan adanya 16 jenis semut dengan total individu mencapaiÂ 14.913. Jenisâ€“jenis yang sangat dominan dalam kawasan yakni Odontoponera denticulata, Pheidole megacephala, Technomyrmex albipes, Tetramorium simillimum, Tetramorium bicarinatum, Tapinoma melanocephalum, Paratrechina longicornis dan Anoplolepis gracilipes. Total keragaman jenis semut 2.789 tergolong sedang dengan penyebaran jumlah individu semut dan tingkat kestabilan komunitas sedang. Keragaman semut dipengaruhi oleh intensitas cahaya matahari, suhu, kelembaban, angin, air dan musim. Diduga perbedaan suhu mikro, iklim, cahaya, kelembaban, pola makan, kompetisi interspesifik, variasi ketersediaan sumber makanan, kualitas habitat dan aktivitas manusia yang memengaruhi keragaman semut dalam areal pemukiman hutan lindung Sirimau Ambon. Ditemukan 3 jenis semut yang invasif yakni Soleonopsis geminate, Paratrechina longicornis dan Anoplolepis gracilipes.
